[Fadiikhan]

HI TO ALL EXPERTS,

Run it in a virtual machine, and have the machine's date set to something that's valid.

VirtualBox is free and works great with all versions of DOS and Windows I've ever tested. And you don't need a modern Windows version. Your old Windows 2000 Professional, or Windows 98 will work for your old app. You could even run it in MS-DOS 6.x if you wanted. DOS works great in VirtualBox.

Lots of solutions that don't involve decompiling or reverse engineering.

The programs said to be around 20 years old.
In one of his PRGs, I see contact number of a person which mentions 'WhatsApp' !!!
Is that the Facebook WhatsApp that we're using now?
WhatsApp..? 20 years back..?
